KR1201 CBCT oral cone beam performance testing phantom

Overview

CBCT oral cone beam performance testing phantom NY-620 is used for oral cone beam CT (oral and maxillofacial cone beam computed tomography) equipment quality control performance testing. The phantom is used to detect the image uniformity, high contrast resolution, low contrast resolution and ranging error of oral CT machines and oral cone beam CT machines. Meets the "WS818-2023 Cone Beam X-ray Computed Tomography (CBCT) Equipment Quality Control and Testing Standards" and "T/WSJD8-2020 Oral Cone Beam CT Quality Control and Testing Standards".
